IMPROVEMENT IN lCARRIAGE-HOLDBACKS.

The Schedule referred t in these Letters Patent and making parl: of the same.

I, WILLIAM RoNDnAU BAKER, of Wellington Square, in the county of Halton, inthe Provnce of Ontario, Dominion of Canada, have invented certain new and .useful Improvements in Holdback-Hooks for Oarriage-Thills and. Shafts, to be called or known as W. R. BAKERS Safety Holdba'ck'and Universal Hook. Y

The nature of my invention relates to an improved holdbaek-hook for carriage-shafts, constructed in such a manner as will also answer as a whifdetree-hook, a neck-yoke hook, a back-hand hook, and a snaphook, being a simple yet ecaeicus device, withoutV springs or complications of any kind, and calculated to save muchtime andltroulble in harnessing and unharnessing horses. Figure l represents a side view of my invention as 'a holdback-hook.

Figure 2, a top view of same.

Figure 3 is a side view of my invention used as a back-hand hook;

Figure 4, as a whietree-hook;

Figure 5, 'as a ,neck-yoke hook;

Figure-7, as a snap-hook.

F, tlg. 1, represents a section of a shaft, upon which is secured, by the screws g g, the holdback-hook A.

B is a double-flanged slotted roller, revolving in the inside of the hook A, having a slot cut in one side of it, as shown by the dotted lines.

The breeching-strap is secured as follows:

The squareeyed hook C, to which the above-mentioned strap is fastened, is entered at the front of the device at the opening marked d, and both it and the rollerB are turned back when they assume the position as shown in fig. 1. The breeching-strap is then secured.

The manner in which the revolving double-flanged roller B is secured in the hook A is as follows:

It is cast solid with one flange, and in that condition is easily placed in the curve of' the hook A; the other ilange isthen riveted on in the usual way.

lr lr, fig. 1, represent small projections in the ange that tit into corresponding holes in the roller to prevent the possibility of the riveted flange from becoming loose.

'lhe roller B is made to fit the hook so as to revolve with ease, and at the same time remain in any position desired.

When the breeching-strap is hooked the whole presents the appearance as ing. 1.

In unharnessing a horse the traces only require to be unhooked and moved forward out of the shafts;

the. roller BI revolves, and the transverse-eyed hook C of the' brceching-strap eis releasedat the point marked d.

same transverse-eyed hook attached. It enters'at the. opening marked d, and the slot indicated by the dotted lines is turned upward with the revolution 4of the roller until the strap is perpendicular, where it remains stationary, as indicated by g. 3.

The hook is simply screwed to 'the shaft at the point immediately under the back-band.

Fig. 4 represents a socket, L, cast to the holdbackhook, adapted-as a whiiletree-hook.

-The end of the whiletree J is rmly inserted in the socket L, the slotted' revolving` double-iianged roller B revolving in the hook A, as in figs. 1, 2, andl 3.

K represents a cock-eye. It is secured to the hook A by drawing it back and entering it at the opening d, when the revolution of the roller carries it to its proper position,as shown by the dotted lines K, iig. 4.

This provides for a simple, durable, and efficacious Whiet-ree-hook.

Fig. 5 represents the saine device used as a neckyoke hook.

i is a socket cast to the hook A, and fastened to the neck-yoke h.

The breast-strap m m passes throughA the double square-eyed hook e, one eye of which enters the slot of the roller B, as before mentioned, for the holdback.

Figure 6V representsa top view of the double squareeyed hook.

Figl 7 represents the same device as a snap-hook.

' B i's the slotted roller revolving inthe hook A, which has an eyed shank, M, at one end, through which any strap may pass, as o. n is a side view of a ring, which enters the slotted roller at theopening d in 'the same manner as the others. The advantagesattending the luse of my device are as follows:

First, as a holdback-hook it is simple in construction, safe in use, easily hooked and uuhooked, free from any danger of getting out of order, as there are no springs of any kind, which' are so objectionable in devices of this nature. In case of accident a horse can'beeasily released. It is also placed diagonally on the shaft parallel with draft of the breechiug-strap,

yoke hook, which allows horses to be released froml vehicles when desired under all circumstances.

Fifth, as a snap-hook it is always reliable, as no spring is used'in its constructiony The hooks can be made of malleable, cast-iron, brass, or other metal.

Disclaiming all else,` What I claim as my invention consists in 1. The arrangement and combination of the doubleanged slotted roller B and hook A, substantially as and for the purpose described, or any other purpose to which it can be applied.

AA2. rlvhe combination of the hook A and socket t' L,

gs. 4 and 5, as shown, for the purposes set forth and Y specified.
